It doesn't matter where you drill, but be aware that there are rock monsters that will eat your crystals. Once you have done this, you can start drilling on a large scale. If your Support station is destroyed, you may run out of air before you can rebuild it.įirst build a support station, and then surround your base with electric fences. Note that your oxygen runs out *extremely* fast in this level. Slugs only start appearing when you've collected around 10 crystals, and Rock Monsters only start appearing when you drill into their caverns, thus you can take your time preparing your men and your base before the carnage begins. Since the level has a finite number of crystals in it total, it's possible to lose so many to the slugs and monsters that you can't win. The problem is that the level is infested with slugs and rock monsters, both of whom eat energy crystals - and when they do, that crystal's gone for good. In this level, your only goal is to collect 45 Energy Crystals.
